Structural Characteristics Of Banksia Woodland Along An Ecohydrological Gradient, Western Australia, Rebecca Thomas Jan 2009

Structural Characteristics Of Banksia Woodland Along An Ecohydrological Gradient, Western Australia, Rebecca Thomas

Theses : Honours

Water availability (the defining feature of a 'hydrological habitat') has a major effect on plant growth, and the physiological and structural characteristics of plants often reflect the availability of this resource. In relation to development of vegetation structural characteristics as a consequence of a given hydrological habitat, it is important to understand whether self-organisation of plant cover (productivity, structure and function) interacts with water availability and if adjustment to water limitation exists ('ecohydrological optimization' or establishment of a 'hydrological equilibrium'). This study tested, through three hypotheses, whether structural and functional attributes of Banksia woodland vary with water availability, i.e. whether …


The Distribution And Long-Term Change In Banksia Ilicifolia Communities On The Gnangara Mound, Ryan Gurner Jan 1998

The Distribution And Long-Term Change In Banksia Ilicifolia Communities On The Gnangara Mound, Ryan Gurner

Theses : Honours

The Gnangara Mound is a large shallow groundwater aquifer which occurs in the superficial formations bounded by the Swan River, Ellenbrook, Gingin Brook, Moore River and the Indian Ocean on the northern Swan Coastal Plain. To protect terrestrial vegetation on the Gnangara Mound. groundwater levels must be maintained to allow plants access to water which is required for their survival. In areas with a shallow depth to groundwater, studies have shown that groundwater drawdown (reduction of the water table by any processes or factors) has a high potential to impact on the vegetation (Havel. 1968: Aplin. 1976: Heddle. 1980a: Dodd …
